If you've ever deposited funds into a staking pool chasing a juicy yield, only to watch that yield shrink week after week, you're not alone — and you're not doing anything wrong. That's just how most staking rewards are designed to work.
Where the Yield Actually Comes From
APY (Annual Percentage Yield) in a staking pool can come from a few different places: trading fees, network rewards, or — very commonly — token emissions. Token emissions are when a protocol hands out its own newly created tokens as a reward to attract depositors early on.
Think of it like a new café giving away free pastries to get people through the door. The pastries are real, but they're not going to keep coming forever. Once the promotion ends, the queue gets shorter.
Protocols do the same thing. They front-load rewards to build TVL (Total Value Locked — the total amount of money deposited in a pool) quickly, because a larger pool looks more credible and attracts more users. But those emission rates are almost always set to decrease over time, either on a fixed schedule or as the pool grows.
What "Front-Loaded" Means in Practice
When a pool is new and small, the token rewards are spread across fewer depositors, so each person's share looks enormous. As more people pile in — drawn by that same high APY — the rewards get diluted across a bigger pool. The APY falls. This is normal, expected, and worth understanding before you commit.
There's a second layer of risk too: the reward tokens themselves have a price. If the token being handed out as a reward loses value — which newer, smaller tokens often do — the real-world return shrinks even further, regardless of what the APY figure says. APY is not the same as profit.
How to Think About Sustainability
A useful question to ask about any yield: if the token emissions stopped tomorrow, what would remain? If the answer is "almost nothing," the yield is almost entirely speculative. Pools backed by genuine trading fee income or protocol revenue tend to be more durable, even if their APYs look less exciting at first glance.
Comparing pools side by side — looking at TVL, the source of yield, and how long the pool has been running — gives you a clearer picture than the APY number alone. The comparison table is a practical starting point for doing exactly that, at your own pace.
